The Wisconsin Department of Transportation (WisDOT) is in the process of developing plans for proposed improvements on the Main Street Bridge on US 45 over the Fox River in the city of Oshkosh, Winnebago County. The purpose of this website is to provide information regarding the proposed improvements, describe the potential impacts it would have on the community, and offer an opportunity for public comment.
Project location
The Main Street Bridge (B-70-56) over the Fox River and approaches, the city of Oshkosh, Winnebago County.
Project purpose and need
The structure is safe for vehicle and pedestrian crossing. The purpose of the project is to preserve the operation of the structural, mechanical, and electrical components of the US 45 Main Street Bridge.
The existing structure and its mechanical and electrical elements have received various repairs and maintenance over its lifespan, but the structure has become deficient due to varying levels of deterioration. Many of the elements are deteriorated or have exhausted their useful service life. These include structural, mechanical, hydraulic, and electrical components.
Anticipated Benefits
The following anticipated benefits are expected following the project’s completion:
- Decreased maintenance costs associated with the structure
- Improved operation of the movable span
- Extending the life of the existing structure by replacing deteriorated and worn-out components
Proposed improvements
Proposed improvements include:
- Rehabilitate existing electrical, mechanical, hydraulic, and structural components of the bascule span
- Minor repairs to the operator’s house and access platforms
- Scarification (removal) and overlay of the approach span concrete deck
- Removal and replacement of the steel grid deck on the movable span.
Traffic impacts
